HBO has given "Game of Thrones" fans yet another glimpse on what can be expected when the show returns on 6 April.

A new trailer of "Game of Thrones" season 4 was aired on HBO just before the finale season of "True Detective" on Sunday and fans are thrilled with what they saw.

The trailer focuses on loss, especially that of the Stark family's, and the consequences of previous actions.

The opening shots of the trailer show Cersei questioning what good power is, if one cannot protect their loved ones. Jon Snow wonders why the world has suddenly fallen apart and Sansa is grieving for her family after the Red Wedding.

Dany is also seen stating her intentions to fight injustice with justice. And, now that her dragons are all grown, she is sure to use them to her advantage. Season 4 will showcase a new side of Dany's, that actress Emilia Clarke described as darker and confident one from the previous three seasons.

Struggles for families that have emerged victorious and unexpected triumphs for the vanquished can be expected when season 4 returns.

Meanwhile, Lena Headey, who plays Cersei in the series, told Vulture that a reunion with Jaime Lannister is on the cards for Cersei.

"It's horrendous. It's kind of crazy. Interesting to film, because we were ... she's in deep pain, and he wants her, because he missed her, and he needs to know she wants him. It's just a weird, fucked-up moment. It's quite mad!" Headey said.

The plot synopsis of the first four episodes of season 4 has also been released. Check them out below.
